Glass reactoris a common and important equipment in chemical laboratory and industrial production process. With the continuous development of technology, there are single, double, and triple glass reactors. Although they are all based on glass materials and have similar basic functions, there are significant differences in their structure, working principle, and scope of application.

Single-layer glass reactor

·Structure and characteristics 

A single-layer glass reactor is a kind of container commonly used in chemical test and substance-mixing processes. It is usually made of borosilicate glass with good corrosion resistance and has the following characteristics:

Simple structure, convenient operation, and maintenance.

Suitable for basic chemical reactions and tests.

Relatively low cost and well suited for small-scale laboratory use.

·Application areas of single-layer glass reactor

Laboratory teaching and scientific research: small-scale experiments in chemical, biological, and other laboratories.

Pharmaceutical industry: preparation of raw materials or intermediates of drugs.

Food processing: e.g. synthesis of spices, food additives.

Double-layer glass reactor: structure, characteristics and application analysis

Double-layer glass reactor

·Structure and characteristics 

Double-layer glass reactor adds a layer of container on the jacket of a single-layer container. A sandwich is formed between the two vessels, which can be heated by injecting heat transfer oil or water to provide better temperature control. The double-layer glass reactor has the following features:

Good isolation performance to keep the internal temperature stable.

Higher corrosion resistance for a wider variety of chemical reactions.

A wide range of capacities are available for selection.

·Application areas of double-layer glass reactor

Chemical industry: preparation of organic synthetic products, and polymer materials.

Oil and gas industry: catalyst research, hydrogenation reactions, etc.

Laboratory and large-scale production: experimental or production processes to meet the needs of different sizes and capacities.


Three-layer glass reactor

Structure and characteristics

Three-layer glass reactor adds a layer of container on the basis of a double-layer glass reactor. A vacuum sandwich is formed between each vessel to provide better isolation and reduce the influence of the external environment on the internal temperature. The triple-glass reactor has the following characteristics:

Excellent isolation performance, minimizing the impact on the external environment.

Excellent corrosion resistance for demanding chemical reactions.

A wide range of capacities is available.

·Application Areas of Triple Glass Reactor

Chemical industry: fine organic synthesis, high-temperature and high-pressure reactions, etc.

Pharmaceutical and biotechnology: preparation of high-purity drugs or biological products.

Laboratory and mass production: to meet the needs of complex experiments and mass production.


There are significant differences between single, double, and triple glass reactors in terms of structure, working principle, and scope of application. A single-glass reactor is suitable for small-scale laboratory tests, a double-glass reactor is more suitable for medium-scale chemical processes and industrial production, and a triple-glass reactor is more suitable for complex chemical processes. In the future, with the advancement of technology, we can expect more new types of glass reactors to meet the ever-changing needs.
